Portrait of Niebla antiqua, an abelisaurid from Late Cretaceous Argentina, for my friend's Birthday. This theropod is known by incomplete cranial and postcranial remains, including braicase and scapulocoracoid. Estimated length of holotype is 4-4,5 meters, and this was adult. Niebla is one of two currently known abelisaurids of Allen Formation (second is Quilmesaurus). This head reconstruction ids based on known remains and skulls of more complete abelisaurid specimens (mainly the Carnotaurus sastrei holotype). I drew highly keratinized skin on its face. This is supported by osteological correlations of abelisaurid snout bones. Exposed teeth are speculative.
